I met the same problem.
ItunesConnect page only show my books are available on 32 stores.
But by this link, free books should available at all stores:http://support.apple.com/kb/TS3599

Right now, it seems that Apple defines free books as books they upload themselves (Apple own books or free give aways, etc).
Does not seem that we can upload free books to other stores. These caught me by surprise!
